LGSOT12CLT1G

LRC · ESD And Surge Protection (TVS/ESD) · SOT-23

LGSOT12CLT1G from LRC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1 passive One of the two unidirectional Transil terminals; it clamps positive transients just above the logic supply level and negative transients to a diode drop below ground, and pins 1 and 2 can be connected together for bidirectional use.
2 2 passive The second unidirectional Transil terminal, with the same clamping behaviour as pin 1 for ESD protection of data and transmission lines (IEC61000-4-2 15 kV air, 8 kV contact).
3 3 passive Common terminal of the dual suppressor array shown on the SOT-23 pin drawing; the datasheet does not explicitly name its function, though the application note describes the array as connected between the signal line and ground.

  • Symbol: LGSOT12CLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lgsot12clt1g-etched.step / lgsot12clt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lgsot12clt1g.step / lgsot12clt1g.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
